REUBEN B. TEETER, OF LOS ANGELES, CALIFORNIA.

CASEMENT WINDOW.

Application filed May 22, 1922.

T all whom it may concern:

Be it known that I, REUBEN B. Tnn'rnn, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a certain new and useful Casement Window, of which the following is a specification.

This invention relates to a window construction and has especial reference to a window sash carried by and opening and closing on hinges affixed to the upright side of the frame, an object of this invention being to provide a simple and economical casement window construction, wnich will effectively exclude rain and drafts and may be used with any form or design of casement window without altering the same.

Another object of the invention is to provide in combination with a casement window, a simple mechanism for operating the same.

My invention consists primarily of a frame having a rabbeted stool or recessed seat, a window sash adapted to fit in the rabbet or recess of said stool, whereby when closed, the bottom of the window sash rests on a lower plane relatively to the stool than when open, and a means for elevating or lifting the window sash from the recessed seat or stool to enable same to clear the stool when opening the same.

These and other objects are attained by the device represented in preferred form in the accompanying drawing, in which Fig. 1 is a sectional side view showing the invention as applied, dotted lines indicating the elevated position of the sash and the relative position of the operating mechanism.

Fig. 2 is a fragmentary front view of the sash showing the applied mechanism.

Fig. 3 is a plan view of one of the hinges used in connection with the sash, and

Fig. i: a rear view of one of the hinges.

Referring in detail to the drawing, 1 indicates a window sash, adapted for opening on hinges affixed to the upright frame memher 2. Each hinge 4, shown in Figs. 8 and =1, for purposes of this invention, is so co11- structed that the leaf 5 thereof is movable vertically and horizontally relatively to the other leaf 6 and with the sash 1, and for this purpose the butts 5 and 6 of the hinges are formed within interfitting ofisets 7 normally occupying the position indicated in Fig. 4;, when the sash is closed or in the res Serial No. 562,719.

cessed stool. When the sash is elevated as hereinafter described, and moved inwardly for a small distance, the respective offset butts 5 and 6 occupy substantially the po sition shown in Fig. 3, in which position the window sash may be swung readily, without interference by the offsets, and clear the stool. In other words, when the sash is elevated and the offsets in the butts 5 and 6 of the hinges are out of register, the window may swing normally and freely on the hinges, which form then the sole support for the window; but, when the offsets in the hinge butts are brought into register or alinement by the closing of the window, the window will drop into its stool or recess.

The lower rail 8 of the sash 1, is preferably beveled on its inner side, as shown at 9, and conforms with a similarly beveled wall 10 of a rabbeted or recessed stool 11, constituting part of the window frame. Onto the face of the stool 11 is secured a thrust plate 12, for purposes to appear presently.

Onto the stile 13 of the window sash is preferably fastened in any suitable manner a case 14, in which is journaled a shaft 15, mounting a sleeve 16, provided with a plurality of teeth 17 that are arranged for engagement with the rack portion 18 of a rod 19, constituting substantially a fulcrum. On said sleeve 16 is also a tooth 20 which is arranged to engage the lug 21 formed on a bolt 22 that is normally held projected in a strike 23 provided in the window frame, by a spring 2 1. On the shaft 15 is a handle or lever 25 whereby the sleeve may be operated with respect to the rack rod 19 to lift the sash out of the recessed stool 11 and simultaneously withdraw the bolt 22 from the strike 23. On the rail 26 of the window sash is preferably fastened a housing 27. in which extends the rod 19, which is threaded at its lower end. to receive an. internally threaded thrust block 28, extending through an opening in the bottom of the housing 27. On said rod 19 and within said housing 27 and bearing against the upper wall thereof is threaded a nut 29, by means of which ti a. thrust block 28 is held projected a determinate distance beyond the housing. Within the housing and surrounding said thrust block 28 is a spring 30 bearing against the nut 29 and the bottom of the housing and arranged to return the rod 19 and lever 25 to normal position indicated in Fig. 2, when,

the handle is relased. This thrust block 28 operates against the thrust plate 12, and obviously when the handle or lever 25 is moved to the position shown in dotted lines Fig. 1, the entire sash is elevated to a position in line with the surface of the stool 11, whereupon the window may be swung open inwardly.

What I claim, is:

A frame having a recessed stool, a window sash, seated in the recess of said stool when closed, a connection between said sash and frame to permit vertical movement of said sash relatively to the recess in said stool and to provide a normal swinging support for the sash when out of said recess, and means for lifting said sash out of said recess and onto the normal swinging support comprising a thrust rod mounted on said sash and engaging said stool, and a means for operating said window relatively to said thrust rod.

In testimony whereof I have set my hand.
